Hi,
I have bought a pair of Bosch 400s for a hw, I know I am suppose to modify the magnets but I can't figure out what I am supposed to do- I read that you have to glue in te magnets and rotate them so that it goes equally fast in both directions but I can't figure out how to rotate the magnets? Also should I be able to just pull out the shaft in the middle with the coil on it- I think you have to to take out the magnets?
Here is a picture:

Thanks,
Max
